Title: Improvements relating to the separation of gases from mixtures thereof
IPC: B01D53/14
Filed: 1927-04-23
Abstract: 270,287. Urbain Corporation. May 1, 1926, [Convention date]. Diffusion apparatus for gases; gases, separating mixtures of.-In a process for the separation of a gaseous mixture by adsorption and diffusion, the mixture is traversed by a jet of gas or vapour containing very fine particles, such as drops of the condensed vapour or solid particles which may be previously activated, the constituent having the greatest rate of diffusion and adsorption being carried away by the jet. In the form shown in Fig. 1, a jet of mercury or water vapour, wherein drops are produced by condensation or atomization, passes from the tube A through a container R and out at a second tube B. A tube C serves for the admission of the gaseous mixture, some of which enters the jet by diffusion and is adsorbed by the drops, the remaining portions of the mixture leaving by a tube D. In a modification, the gases are delivered into the stream of vapour by a jet C<1>, Fig. 2, those constituents that diffuse the more readily and are less easily adsorbed passing through the stream and out at the delivery tube D<1>, the remainder being carried away by the stream of vapour and delivered by the tube B<1> or an outlet E. Either or both the devices shown in Figs. 1 and 2 may be connected in series or in parallel and the separation may be modified by varying the speed and pressure of the gaseous mixture, the speed and nature of the traversing jet, the temperature, and the dimensions of the conduits for the jet and gaseous mixture. An apparatus embodying the invention is shown in Fig. 3 wherein the gas, stated to be a mixture of carbon monoxide and hydrogen, is fed by a tube C<1> into the interior of a tube A<1> containing mercury vapour generated from mercury in a vessel D. Below the tube A is actuated, in a vessel S, a tube B<1> of narrower cross-section than the tube A<1>, the tube B<1> communicating with a receiver T connected by tubes E, F to the vessels S, D respectively. The whole is surrounded by water maintained at a level x, y in a container R. Drops of mercury are formed in the vapour by condensation and a gas mixture richer in hydrogen which has diffused into the outer part of the vapour stream passes off by the tube P, the mercury condensed in the vessel S passing away by the tube E. The gas mixture poorer in hydrogen, carried down the tube B<1>, passes off by the tube Q, condensed mercury being returned to the vessel D.

Title: Potentially reactive liquid coating compositions
IPC: C09D161/06
Filed: 1926-04-27
Abstract: 267,736. Marks" E. C. R., (Bakelite Corporation.). April 27, 1926. Phenol - aldehyde condensation products; phenol-oil reaction products. - In preparing liquid coating compositions, a phenol-oil composition is first produced by heating together a phenolic body such as phenol or cresol, a vegetable oil such as tung oil, and a small proportion of a converting agent. A suitable converting agent is phosphoric acid or anhydride, hvdrochloric, sulphuric, or oxalic acid, pyrogallol, acetic anhydride, anhydrous aluminium chloride, sulphur, sulphur chloride, or antimony sulphide; the converting agent should not exceed 3 per cent by weight of the phenol used. The greater the quantity of oil used in the reaction the more plastic will be the final product. Oils such as linseed, soya-bean, rape-seed, perilla, castor and fish oils may be used instead of tung oil. To the phenol-oil composition is added hexamethylenetetramine. If added in proportions such as 5-14 parts by weight to 100 parts of original phenol, the resulting composition is non-reactive, but it may be rendered potentially reactive by dissolving it in a solvent such as turpentine and adding a further quantity of hexamethylenetetramine preferably such that the total quantity thereof is about 20 per cent bv weight of original phenol. The solution is slowly heated to 125- 135‹ C. to effect partial reaction and to stabilize it. If desired sufficient amount of hardening agent may be added in the first instance to yield a potentially reactive product.

Title: Electric Metallurgical Furnaces.
Inventor: TURNER ANDREW
IPC: C21B13/12
Filed: 1916-08-16
Abstract: 111,120. Turner, A. Aug. 16, 1916. Cyanides and cyanamides are obtained' in the production of iron and steel by the use of three electric furnaces in conjunction. One is a cupola furnace m, in the wall of which are embedded two circular inducing coils n and a connecting helical coil e. A circular channel c communicates with the top of this furnace by radial channels furnished with gates g so that molten iron can be allowed to fall freely through the cupola to its hearth, while being subjected to the action of the embedded coils n, e. Horse-shoe shaped electromagnets h are let into the masonry below the circular channel c so that each limb is below one of the radial channels. A pas. sage leads to the circular channel c from a reverberatcry furnace a mounted on the scaffolding of the cupola, and another passage l connects the cupola hearth with a lower reverberatory furnace a<1>, both passages including rotary valves b<1>, b. Inducing conductors are embedded in the hearth of each reverberatory furnace. The furnaces are first heated and dried electrically or otherwise. A light charge of lime, ore, and fuel is then fed into the cupola hearth from a hopper at the top of the furnace and the two reverberatory furnaces are supplied with lime iron ore fluxing material for refining purposes. Next, the upper reverberatory furnace a is filled with crude molten iron from an external source. This iron runs through the circular channel c and radial channels and falls freely through the cupola, drawing in air from tuyeres f situated between the two circular coils. Gases containing cyanogen and alkali carbonates are generated in the hearth of the cupola furnace and are led by pipes k to the reverberatory furnaces, where cyanides and ferro-cyanides are obtained. If these furnaces are supplied with a mixture of lime and coke as used for carbide manufacture, cyanamides are produced. Specification 7302/92 [Class 72, Iron &c.] is referred to. Waste gases are passed through a boiler, and the steam may be used for working an engine which drives a dynamo supplying current for the furnaces.

Title: A process for the purification of acrylonitrile
Filed: 1959-04-06
Abstract: Acrylonitrile containing methyl vinyl ketone as impurity is purified by treating at elevated temperatures in the acid pH range with a thiocarboxylic acid, an organic thio acid amide or an organic compound containing a mercapto group, and isolating the acrylonitrile from the resulting mixture by fractional distillation.  Suitable compounds for use in the process are, for example, n-dodecyl mercaptan, tert-dodecyl mercaptan, octyl mercaptan, mercapto propionic acid, thiopropionic acid, thiophenol and thiourea. Preferably the pH value of the mixture is between 1 and 4 and the desired pH can be obtained by adding, for example, sulphuric acid or toluene sulphonic acid, either before or after the addition of the thio compound to the acrylonitrile.  The process may be carried out continuously and if desired stabilisers, such as cyclohexyl pyrocatechol, tertiary-butyl pyrocatechol and phenthiazine may be added to the mixture to prevent polymerisation of the acrylonitrile.

Abstract: 1505463 Synchro shaft rotation rate SUNDSTRAND DATA CONTROL Inc 23 March 1976 [27 May 1975] 11733/76 Heading GIN A circuit for generating a signal representing this comprises means 10, 12, 16 for generating signals representing the cos. and sin. of the synchro shaft angle #, means responsive to these for generating signals representing or approximating tan. # and cot. #, means 38, 58 differentiating the tan. and cot. signals respectively to produce first and second rate signals and means 62 responsive to the sin. and cos. signals for selectively connecting one of the rate signals to an output. The angular position of the shaft represents barometric altitude. The cos. signal on line 14 and reference voltage VR are applied to summing junction 22 of integrator 24. Comparator 26 compares the resulting integrated signal with the cos. signal to control switching transistors 20, 28. The resulting output A from filter amplifier 30 would be VR tan. # but due to feedback through function generator 34 is made directly proportional to # over part of the cycle. Signal B is a similarly linearized V R  cot. # signal. According to whether cos. # or sin. # is the greater (see Fig. 4), the corresponding output 32A or 56B will be linear. The output 66A of comparator 62 controls switch 64 to connect the corresponding line 40 or 60 so that the output rate signal is directly proportional to the rate of rotation of the shaft. Detectors 76 and 78 are used to detect excessive outputs from integrators 24, 44. If NAND gate 80 receives a high signal from both detectors due to circuit failure, it switches off a validity signal.
